Testing capacity of an older battery pack?

<< < (3/3)

John Rist:
Early on, in my venture into electric power, I fried a motor by trying for a full run on the ground.   We have things set up near the high limit of motor capacity to save weight.  I don't know how much harder a ground run pushes a motor.  But in most cases it is fetial.   n1  If you want to check out a timer's settings with a full run remove the prop or put on a small prop.   y1

Dennis Toth:
Ok I got it. Plan "B" - 10 sec ground test to check rpm and current. If good, will do level flight test and check battery capacity. If good, will proceed to half OTS pattern test, then check capacity. If good, will do short (1lap between) OTS pattern, then check capacity. If good, fly full normal OTS pattern then check capacity. If any step is bad - buy new pack.

Best,    DennisT
